can anyone help with one or two of these questions? ill give brainliest
Answer:
1. 1.00(1/2)^151/30.2= 31.3 g
2. 24g-->1.4 g = 4 half-lives, so 4*5730= 22920 years
3. 64g-->2.0g = 5 half-lives, so 12.5/5= 2.5 hours

Molecular chaperones can work by creating an "isolation chamber." What is the purpose of this chamber? Question 6 options: The chamber acts as a garbage disposal, degrading improperly folded proteins so that they do not interact with properly folded proteins. This chamber is used to increase the local protein concentration, which will help speed up the folding process. This chamber serves to transport unfolded proteins out of the cell. This chamber serves to protect unfolded proteins from interacting with other proteins in the cytosol, until protein folding is completed.
Answer:
Providing them with a suitable hydrophobic environment for correct folding
and return to its native form
Explanation:
The chamber serves to protect unfolded proteins from interacting with other proteins in the cytosol until protein folding is completed.
Chaperones, also known as heat shock proteins, act to correctly fold proteins after their synthesis.Some of the most important chaperones include Hsp60, Hsp70 and Hsp90.Thus, chaperones prevent proteins from aggregating into nonfunctional structures.In conclusion, the chamber serves to protect unfolded proteins from interacting with other proteins in the cytosol until protein folding is completed.

How is the atmosphere a system, include components, inputs, outputs & flow.
Answer:
the flow in systems besides the flow.
Explanation:
Answer:
When studying Earth as a whole, our primary input is energy from the sun and from space. Earth outputs heat and light to space, maintaining an approximate overall steady-state with respect to energy.

A major difference between eukaryotes and prokaryotes is that __________. A major difference between eukaryotes and prokaryotes is that __________. some eukaryotic cells live in areas of temperature extremes whereas prokaryotic cells cannot prokaryotic cell structure is much more complex than eukaryotic cell structure eukaryotes were the first cell type on Earth eukaryotic cells contain the genetic material DNA whereas prokaryotic cells contain RNA eukaryotes' survival is limited to a few environments whereas prokaryotes have adapted to a variety of environments
Answer:
All life on Earth consists of either eukaryotic cells or prokaryotic cells. Prokaryotes were the first form of life. Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.
The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure. Eukaryote DNA consists of multiple molecules of double-stranded linear DNA, while that of prokaryotes is double-stranded and circular.
